使用Django REST发出POST请求时，验证的_数据为空

Question

我正在尝试使用Django REST framework在我的数据库中创建一个新条目，我能够成功地发送请求，但是validated_data是空的：

# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.shortcuts import render
from rest_framework import viewsets
from django.shortcuts import get_object_or_404, get_list_or_404
from .models import GetPurchases, CarFax
from .serializers import PurchasesSerializer
from .serializers import CarFaxSerializer
from rest_framework.response import Response

# Create your views here.


class GetCarFax(viewsets.ModelViewSet):
    ''' This view will be used for POSTing new carfax reports to the database '''

    queryset = CarFax.objects.all()
    serializer_class = CarFaxSerializer
    # authentication_classes = []
    permission_classes = []
    #print('TEST')

    def list(self, request):

        # accessed at url: ^api/v1/carfax/$
        queryset = CarFax.objects.all()
        serializer = CarFaxSerializer(queryset, many=True)

        return Response(serializer.data)

    def retrieve(self, request, pk=None, *args, **kwargs):
        # accessed at url: ^api/v1/retrieve/{pk}/$
        queryset = CarFax.objects.all()
        record = get_list_or_404(queryset, vin__exact=pk)
        serializer = CarFaxSerializer(record, many=True)

        return Response(serializer.data)

    def create(self, request, **validated_data):
        print('TEST')
        print(request.data)
        print(validated_data)
        serializer = CarFaxSerializer(CarFax.objects.create(**validated_data))
        headers = self.get_success_headers(serializer.data)
        print(serializer.data)

        print(headers)
        return Response(serializer.data, headers=headers)

在序列化程序.py在

^{pr2}$

当我打印request.data时，我可以看到我发送的数据。但是validated_data是空的，这是我用来创建模型的dict。在

首先，您的GetCarFax类似乎很混乱：（因为您将重写大多数方法，但它没有为视图提供任何优势。所以把你的GetCarFax视图类改为下面的

class GetCarFax(viewsets.ModelViewSet):
    """
    This view will be used for POSTing new carfax reports to the database
    """
    queryset = CarFax.objects.all()
    serializer_class = CarFaxSerializer
    # authentication_classes = []
    permission_classes = []
    lookup_field = 'myfieldname'

这几行代码将为您处理所有CRUD操作：）
